Wow! Thats the first thing i said when i played the first song with this box. This box really brings out the best of my 12w7. It hits the lows so hard but very clean. You can hear the difference in the quality of this box. Every box made here is built with great quality and craftsmanship. I have been a customer of robs for awhile now and i will continue to be a lifetime customer! This might be the best box ever made!!!!
